The present invention relates to gates and has for its principal object to? provide a :vehicle operating. means therefor, whereby to open or close the gate upon the approach 5 of aivehicle I still further object of the invention. is

to construct the-gate of a 'pair of gate sections, -'with'leach of said sections arranged for iverticalswinging vmovement. r I V 10 Another object of the invention-is to provide a vehicle operating means for each of :the

from.

An additional object is to provide operat- 1115 ingmeans for the sections of the gate disposed in advance of each sideofthe gate, and adaptedfor moving the sections into an'open or closed position, depending upon the direction of travel of the vehicle.

1.720 *Another object is to provide an apparatus 0f this character of a simple vand practical construction which is strong anddu'rable, eflicient and reliable" in performance, rela-, tively inexpensive to manufacture-and" asg25 semble in operative position, and otherwise well adapted to the purpose forlwhichthe sameis intended. j fr Otherobjects of the invention will become apparentas the nature of the invention-pronoceeds we and I when taken in connection. with 1 the accompanying drawings.

05 inner'lower edges being provided witha bracket 6 for supporting the ends of a shaft 7, extending between each pair of thelposts and formed; at the: outer lower corner ;of a I gate section 8.

The. gatesections may be I constructed in 7 any manner well knowninithe art, suchias is for instance, a rectangular shaped frames8, having'a wire mesh9 attached to the members of said frame. :If desired, the shaft 7 5 may be hinged, together with theflfr'ameo'f the'gate section or may be formed separately and attached in any suitablemannerto the lower outer edgevof the frame as indicated 7 inFigure/l of the drawings. Braces 10V may7 also be provided for the oppositeends of'the shaft and connectedto the bottom frame member of the gatewand rear-vertical frame members to" prevent bending of the shaft. The twosections of the'gate are formed in 3,5 duplicate and cooperate to. close the entrance therebetween, the respective sections; being mounted on vthe-gate posts. By. reason of the horizontally disposed shaftu'z, extending transversely atthe rear edges of the ga'tefsections, the sections are thus adapted to. swing 1 vertically between the posts 5nandat-each side. ofe vthe entrance. At the inner adjacent edges-of. the gate section is arranged a latch 11," secured at, one enact. the gate and 0 15- 385 pendingvdownwardly-with its'opposite end freelydisposed anuadapted for engagement with a staple 12 whichmay be .embedded in theground. at the." inner edges of-these sec 7 tions A pair of; posts 13, are arrangeld atgao eachfsideaof the gate: and a1 predetermined vdistancetherefrom, Keachpair .of postsbeing v disposed r in" spacedrelation; at opposite sides of .thedriveswayeand are provided adjacent journaled for-rotation. The shaft. '15 ex tends transversely. of thevdri'veways, and inank above the surface of'the ground for engagement by the wheels of the vehicle approaching the gate. Stakes 17 driven in the ground adjacent each end of the crank 16 supports the shaft, in order to prevent the distortion thereof through the weight of the vehicle when passing: thereover. At each end of the shaft is a laterally extending arm 18, to'which' one end of a coil spring is attached with its opposite end secured to a bracket extending from the adjacent post 13, whereby to yieldably retain the crank 16 of the shaft in an upwardly ex- 7 tending position. Adjacenteachgend'ofthe shaft 15 is also arranged an operating lever :21, extending :laterally from .the shaft and .normally disposed vertically when the crank 16' is disposed in a vertical position. A screweye 22 is attached at each side .of the 2(j l6V8I '21, adjacent the lower edge thereof, :the screw .eye remote from theu-gate having .oneend of a flexible operating member 23 attached .thereto, and extending upwardly .over a .pulley '24, rota-tably supported in a bracket 25attached adjacent the upper end 10f the post 13, the operating member then extending .in l a direction :toward the gate and vover a pulley 26 mounted :in a bracket 27 at j the upper outer edge of the adjacent post 5. 30 The opposite-end of the flexible member -231is ithenattached to the :rear frame member of the gate section at a point intermediate :the top and bottom'aedges thereof. To the nether screw eye 22 carried by the operating -s5 @lever '21, disposed :at the side of. such lever, adjacent the gate, is .attached one end of a flexible member 28, which flexible member extends upwardly .over. a pulley '29, also rotatably mounted in the bracket 24 at the upper end;of the :post- 13, where the member .then .exte'ndslin .a direction toward the gate and over a pulley wheel '30 rotatably supported in a bracket 31- .attached at the upper .innervedge -of the adjacent post 5.

i 1 The opposite end'of the flexible member 28 Q-is then attached to a lever v32 pivotally.

mounted along :the' lower edge of the gate section,jintermediate the inner and 1 outer edgesthereof, said lever being adapted for .50 pivotal movement longitudinally.ofj'the loweriedgeoftheggate section. To thefree end of the lever 32' is attached flexible member 33,- extending to the latch "11 of saidtgate section, and adapted upon-the operation of #85 said lever to release the latch from its engagement with the staplelQ, andthus per- I cepti'ble of various changessand gmodificw tions, without departing frQmthespirit-or f mi t v the' upward "swinging; movement of the gate. Each of the Iflexible members 23 and 28 have a weight 34' interposed therein, be-

I :IQ- -t-ween theepuIlley-wheels mounted on thepost 3 55, and :the' connection :of said memberswi-th' theggate whereby to maintain said members in aatautcondition. 7 I V At the lower inner corner ofe'ach: of the f.6i"-.;gat'e sections is arranged a pair of en oportions of the gate. Aguard 38 is proesuch 'forms of ifroaari nally extending brace rods 35 to the intermediateportion of each of which it attached one end of a coil spring 36 and with the opposite ends of the springs attached to the post 5, whereby. to facilitate the vertical swinging movement of the gate. Each of the springs 36 are connected with their respective posts by means of a section of chain 37, whereby to provide for the adjustment of any tension of the spring. The flexible members'23 and 28 may comprise either a chain as illustrated in the present embodi-- ment of the invention or may be in the form of acableor rope for forming the connection between the rock shaft and the respective vide d for each of the :fiexible'members disposed adjacent'the operating lever :21, for the purpose of retaining .saidamembers' in a longitudinally extendedpositionadjacent .the opposite sides of the lever. The upper end of the operating'lever 21 isformed in the shape of a fish tail as shown atx39, with the opposite-ends thereof extendingttransversely with respect to the flexible members so .as to insure an engagementofthe lever therewith upon movement .of the lever in either direction.

.It will'be apparent from-the foregoing that upon the approach of the vehicle toward either side of the gate, the wheelsitliereof, in riding over the crank 16 will rotate the rock shaft and cause the :lever 21*to:move

downwardly ina directiontoward the gate. J The initial movement of this 7 lever upon oo engagement with the flexible member .28will operate to release thelatch 11 and-:thesub- V sequent continued movement of :the lever will operate to raise each of the gate :sec- .tions upwardlyand outwardly zat each'side of the post 5; After the vehicle has passed through the gate and coming into contact. 7 with :the crank 16 of the rock shaft at the ,--opposite side :thereof,which, it will'be understood, is unaffected by the'opening movement 119 of the gate, the lever 21 associated with said last named shaft will move away fromthe gate, for engagement with thefi'exiblefinember 23, whereby "through its connection with j theouter edge of the gate, will gcausejthelns i same to swing upwardly .andxinwardly' into its closed position.
